Which type of ventilator will respond best

to the homeowners’ environment? HRV or ERV?

Depending on your home geographical location, you will need to install one of the following categories

of air exchanger: A Heat Recovery Ventilator (HRV) or an Energy Recovery Ventilator (ERV).

HRV - Heat Recovery Ventilator - Ideal for colder climates

In colder climates, where home heating is essential, the heat recovery ventilator (HRV) is the proper

choice. The HRV keeps the home supplied with a steady ow of fresh outdoor air. As stale, warm air is

expelled, the heat recovery core warms the incoming fresh, colder air before it is distributed throughout

the home. The result is a constant supply of fresh air, no unpleasant drafts and greater home comfort.

In addition to heat recovery and improved air quality, the HRV provides necessary ventilation while

controlling excess humidity.

ERV - Energy Recovery Ventilator -

Year-round ventilation

ERVs are suitable for all climates including those with hot, humid summers, where homes are air-conditioned

and possibly dehumidied during large parts of the year. As the HRV, the ERV recovers the heat in cold

season, however, it also recuperates the energy trapped in moisture, which greatly improves the overall

recovery efciency. The ERV process is as follows: In humid climates and air conditioned homes, when it

is more humid outside than inside, the ERV limits the amount of moisture coming into your home. In dry

climates and humidied homes, when the humidity level is reversed, the ERV limits the amount of moisture

expelled from your home.
